(BUENOS AIRES, Argentina) — The world’s top financial officials called Sunday for more dialogue on trade disputes that threaten global economic growth, with one warning that differences remain and tensions could escalate further. The two-day meeting of finance ministers and central bankers from the Group of 20 nations came as the United States clashes with China and other nations over trade, with the nations imposing tariffs on billions of dollars of the other’s goods. A final communique said that although the global economy remains strong, growth is becoming “less synchronized” and risks over the short and medium terms have increased. “These include rising financial vulnerabilities, heightened trade and geopolitical tensions, global imbalances, inequality and structurally weak growth, particularly in some advanced economies,” the communique said.
